CString截取字符串全攻略
例程1:(csdn)
文件xxxx.dll去掉後面的.dll
方法1、
char str[] = "xxxx.dll"
char*p;
p=strrchr(str, '.');
*p = 0;
方法2、
CString str="xxxx.dll";
int n = str.ReverseFind('.')
str = str.Left(str.GetLength()-n-1);
例程2:(csdn)
取得一個字符串中第一個 '?'號之前的字符
方法1
CString m_char,m_disp;
m_disp="jadfueiuajdf?";
m_char="?";
if (!m_char.IsEmpty())
{
int index = m_disp.Find(m_char);
m_disp = m_disp.Right(m_disp.GetLength()-index-1);
}
返回m_disp就行
方法2
CString temp=the.m_bb;
CString reslut=temp.Left(temp.Find("?")-1);
例程3:(csdn)
一個CString類對象m_StrReceiveModem={ATS0=2
OK $03#}
如何截取從$開始的字符串
方法1
CString m_StrReceiveModem;
int nPos = m_StrReceiveModem.Find('$');
if(nPos >= 0)
{
CString sSubStr = m_StrReceiveModem.Mid(nPos);//包含$,不想包含時nPos+1
}
方法2
CString m_StrReceiveModem;
int nPos = m_StrReceiveModem.Find('$');
if(nPos >= 0)
{
CString sSubStr = m_StrReceiveModem.Right(StrReceiveModem.GetLength()-nPos);
}
}
//截取“$”到“#”的字符串
int first,last;
first= m_StrReceiveModem.Find("$");
last= m_StrReceiveModem.Find("#");
CString sSubStr = m_StrReceiveModem.Mid(first,last);
例程4: (fox)
//根據路徑解析出文件名
CString m_Filepath = "E:\\fox_work\\vc_experiment\\hello.txt"
int nPos = m_Filepath.Find('\\');
CString sSubStr = m_Filepath;
while (nPos)
{
sSubStr = sSubStr.Mid(nPos+1,sSubStr.GetLength()-nPos); //取'\'右邊字符串
nPos = sSubStr.Find('\\'); //不包含'\',函數值返回-1
if (nPos==-1)
{
nPos = 0;
}
}
//最後sSubStr = "hello.txt"
注:CString::Find函數,如果給定的參數是一個字符串,那麼它必須與此字符串中的某一個子字符串完全匹配才能返回相匹配的子字符串第一個字符的索引。
